I'm attempting to migrate an existing server running Debian 5.0.10 following this guide, and I've completed all of the steps, but I can't get it to boot. I tried the deprecated GRUB Legacy kernel option in the Configuration Profile options, but that got me nowhere, so I decided to try Direct Disk. I booted into recovery mode and reinstalled GRUB via chroot, and when I reboot, it's able to load the kernel properly, but then it is unable to find the root device. I've tried different parameters in the GRUB command-line, including /dev/sda1 notation, or UUID={uuid} notation, and it continues to fail, dropping me into busybox. Any ideas?
